Abstract
A method by which a base station reduces an operation for removing self-interference in an FDR environment can comprise the steps of receiving estimated channel state information from a terminal, determining a beam forming value for transmission beamforming on the basis of the received channel state information, and transmitting a downlink signal by applying the determined beamforming value.

1-6. (canceled)
A method for reducing an operation for self-interference cancellation by a user equipment (UE) in a full duplex radio (FDR) environment, the method comprising:
- performing channel estimation for a downlink signal transmitted from a base station (BS);
- determining a beamforming value for transmission beamforming based on channel reciprocity property as a result of the channel estimation;
- and
- transmitting an uplink signal by applying the determined beamforming value.
A base station (BS) for performing communication to reduce an operation for self-interference cancellation in a full duplex radio (FDR) environment, the BS comprising:
- a receiver configured to receive estimated channel state information from a user equipment (UE);
- a processor configured to determine a beamforming value for transmission beamforming based on the received channel state information;
- and
- a transmitter configured to transmit a downlink signal by applying the determined beamforming value.
